It is impossible to find the perfect housemate or guest and how we portray ourselves online is often completely different to how we really are. Facebook should be called, ‘Life edited (to the good parts)’. On the Couchsurfing and other sites, people make their profiles upbeat and lively. We have to advertise ourselves to look appealing and amiable. But someone virtually is a different experience to the reality. It is a big step from seeing someones profile to actually having them in your house in the flesh. Maybe we should be more honest.
